The length of the radius will be 22 units.
<h3>What is the radius?</h3>The radius of a circle is defined as the distance of the center of the circle to its outer layer. It is a locus of a point present at some distance from the center point.
Now from the question, we have an expression:
By solving the above equation we get
Hence the length of the radius will be 22 units.
To know more about radius follow
Lets get started :)
The First question:
Diameter = 20 ft
Radius =
of 20 (diameter) = 20 ft
Area formula of a circle is
A =
r²
=(10)²
=100 ft²
≈ 314 ft²
The answer will be the second option
The Second question:
radius of circle = 12mm divided into 20 sectors area
A =r²
=(12)²
= 144 ft²
Divide into 20 equal sector areas =
≈ 22.6 mm²
Your answer will be the third option
The Third Question:
90°, sector area = 36 , Radius = ?
and cancels out
We can now cross multiply
360 × 36 = 90r²
12960 = 90r²
Divide by 90 on either side
144 = r²
Take squareroot
x = 12 in
Your answer will be the third option
